In Canada August 16, 1938 3 Claims.

The present invention pertains to a novel irnprovernent in a cutter for ensilage and similar materials.

The cutter is a part oi a machine in which the material is fed to be out. The cutter consists of a rotatable body or plate carrying a number of blades. The principal object of the invention is to provide novel and improved means for mounting and adjusting the blades on the body.

Accordingly, the body is formed with a number of vanes, each having a perpendicular flange at one end. Each vane carries a detachable retaining `plate and is so mounted as to have a slight swivel movement towards and from the vane. The blade is laid against the plate and is alined thereon by means of a pair' of lugs on the plate. A

single means is used for securing both the blade and the plate to the vane at the desired distance from the latter.

This means includes a bolt surrounded by a spacer tube which, in turn, carries an adjustable nut bearing against the vane. The position of the nut on tube determines the distance of the plate and blade from the vane. The spacer tube is so constructed as to be accessible for turning at its head, which is disposed behind the Vane. The head is enclosed in a cap, and the securing bolt passes through both the vane and the cap and is fitted with a nut bearing against the cap for drawing the parts together and securing the assembly.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing in which:

Figure l is an elevation of the device, showing the housing in section;

Figure 2 is an elevation of the device at right angles to Figure l;

Figure 3 is a section on the line 'rl-3 oi Figure 1; 4D Figure 4 is a section on the line ll-l of Figure Figure 5 is a section on the line 5-5 of Figure 5 Figure 6 a a detail elevation with the blade removed, and

Figure 7 is a detail elevation with the bearing plate removed.

Reference to these views will now be made by use of like characters which are employed' to designate corresponding parts throughout.

The device of the invention is mounted in a housing I having a discharge spout 2. The material to be cut is fed to the cutting device and,

after being cut, is discharged by means well known in the art and which need not be described in detail here.

The body of the device is in the nature oi the plate 3 suitably mounted on a shaft l to rotate therewith. The plate 3 is formed with several 5 outwardly extending varies 5, each of which is form-ed along one edge with a danse or head ii forming a T-shaped structure.

On each of these vanes is mounted a bladeretaining or bearing plate 'i oi substantially 10 triangular formation and secured at one corner to the corresponding vane b-y a bolt and nut 8. Adjacent to this corner, the vane is formed with a lug 9 engaging the flattened corner l@ o the plate l', as shown more clearly in Figure 6. From the 15 anchored corner, the plate 'l is bent outwardly as indicated by the numeral ll in Figure 4 and has its base flanged at i2 over the edge of the corresponding head 6.

Adjacent to the flange l2, the plate l is bent at 20 i3 to lie in the plane to be assumed by the cutting blade. The flattened portion provides in fact a bearing surface for the blade lil placed against said surface as also shown in Figure fl. The blade is secured to the portion i3 by a. pair of bolts I5 passed through the blade and the portion i3 and tightened against the body l, as illustrated in Figure 5. The heads iti of the bolts are preferably counter-sunk in the blade as shown in Figure 5. The plate 'I is formed with a pair of 30 bearing lugs l'l engaging the rear edge of the blade and thereby holding the blade in proper alinement, as illustrated in Figures l and 6.

Figure 5 also illustrates the construction whereby the plate I and blade M are capable of ad- 35 justinent in their distance from the vane 5 to the extent permitted by the overlapping or" the flange I2 on the head G. For this purpose, the bolt iii is surrounded by a tube i3 extending from the back of the portion I3 through the Vane il. The 40 tube is threaded externally to receive an adjustable nut I9 that bears against the vane and seats in a ring 2t formed on the vane. Thus, the position of the nut on the tube determines the distance of the parts i3 and lll from the vane 45 The endof the tube beyond the vane is formed with a head 2l adapted for engagement by a suitable turning tool. This is equivalent to: turning the nut on the tube. The head 2l is enclosed in a separate cap 22 through which the bolt l5 also passes. The nut 23 on the bolt bears against the cap and thus draws the assembly together.

It will thus be seen that the invention provides a simple means of adjusting the cutting blad-e and its retaining plate with reference to the corre- 55 sponding vane 5 and that the several blades of the device may be separately and differently adjusted if necessary or desired.

Although a specic embodiment of the invention has been illustrated and described, it will be understood that Various alterations in the details of construction may be made Without departing from the scope of the invention as indicated by the appended claims.

What I claim is:

1. In a cutter of the character described, a rotatable body, said body having a ange perpendicular to the plane of rotation, a plate attached to said body and bearing against one edge of said flange, a blade engaging said plate, a bolt passing through said blade, plate, and body, a tube on said bolt and passing through said body, a nut adjustable on said tube and engaging said body, and means for tightening said bolt.

2. In a cutter of the character described, a rotatable body, said body having a flange perpendicular to the plane of rotation, a plate attached to said body and bearing against one edge of said ilange, a blade engaging said plate, a bolt passing through said blade, plate, and body, a tube on said bolt and passing through said body, a nut adjustable on said tube and engaging said body, said tube having a head behind said body, a ycap enclosing said head and bearing on said body, said bolt passing through said cap, and a nut on said bolt and bearing on said cap.

3. In a cutter of the character described, a rotatable body, said body having a substantially radial ange perpendicular to the plane of rotation, a plate attached to said body and bearing against one edge of said ange, a blade engaging said plate and lying perpendicular to said flange, a bolt passing through said blade, plate, and body, and adjustable spacing means on said bolt between said body and plate.
